Product details

Dual-frequency MEMS XO — 26 MHz and 27 MHz on one die

The DSC6121CI2A-00AMT: This dual-output architecture saves a second oscillator footprint and the associated routing — useful when a design needs both a 26 MHz USB PHY clock and a 27 MHz audio or video reference.

Obsolete — sourcing through independent channels

No successor or pin-compatible alternative is listed in the official record.

Frequently asked questions

What frequencies does the DSC6121CI2A-00AMT output?

It provides two CMOS outputs: 26 MHz and 27 MHz, from a single MEMS resonator. Both frequencies are available simultaneously on separate output pins.
